Claims.

This invention relates to tools of the character employed by linoleumlayers and has for its primary object, the provision of a device forspreading paste, cement, glue or the like, upon surfaces over which acovering is to be placed.

One of the important aims of this invention is to provide a pastespreader for linoleum layers,

the character of which insures an even distribu tion of the paste;presents an easily handled holder for a specially molded live rubberstrip; and makes it possible to spread paste along the corners of a roompresented by the meeting of the floor and walls thereof, withoutmarring, scratching or otherwise injuring the woodwork on vertical wallsurfaces.

This invention has for an even further object, the provision of aspreader of the aforementioned character, the grip whereof is formed ofa relatively light yet stiff material and combined with a serratedresilient strip in such fashion as to permit effective manipulation andreplacement.

Other objects of the invention will appear during the course of thefollowing specification, referring to the accompanying drawing, wherein:

Figure l is a side elevational View of a paste spreader made to embodythe present invention.

Fig. 2 is an end elevational view thereof.

Fig. 3 is a vertical cross sectional view taken on line III-III of Fig.l; and

Fig. 4 is an enlarged detailed fragmentary elevational view of a portionof the resilient strip, illustrating the form of notches createdtherein.

In producing a tool for spreading paste or the like, in accordance withthe present invention, the U-shaped holder generally designated by thenumeral 6, is made of an originally flat piece of metal that has beenformed to produce inturned lips 8 along each end thereof and arcuatefaces l9 along the longitudinal edges thereof. When the originally fiatstrip of material, such as aluminum is rebent upon itself, about amandrel or other suitable instrument to produce grip [2, legs 14 arecreated to embrace strip l6. These legs l4 are in spaced relationthroughout their areas and grip l2 projects laterally to each side ofthe outer faces of legs i4.

Strip I6 is made of live rubber and formed to present a number of smallnotches 18 extending inwardly from the free edge thereof. These notchesmay be molded but their size is such as to render molding inefiectivefor desirable results. It has been found therefore, that the use of hotwires is preferable, for notches 18 should be relatively shallow andnarrow to insure the production of minute ridges along the face of thepaste being spread.

The length of strip I6 is greater than the length of lips 8 and the legsI4 of holder 5. The projected portions 20 of strip I6 create buffers ateach endof the spreader for engaging the vertical surfaces 22 of a wall.

Strip I6 is secured in place between legs M by bolts or analogous means24 and inturned lips 8 grip strip l6, as shown in Figs. 2 and 3. If liverubber is not employed in making strip 16, results will not besatisfactory and a breaking Will occur along lips 8 after the spreaderhas been in use a short time.

The extended ends 29 of strip [6 are arched as at 26 to lend flexibilityto buffers 20 and further, to permit that portion of the spreader to beintroduced into cavities below the conventional type molding orquarter-round when linoleum or floor covering is being layed thereunder.With such form, the edges of grip 6 will not come into contact with themolding to mar or scratch the same.

Legs M are in spaced relation as aforesaid to permit cleaning the toolwhen desired. No cavities or openings capable of catching and holdingpaste are present in this tool when formed as illustrated and described,and washing is quickly accomplished when grip I2 is hollow and legs I4are spaced apart.

In practice, pressure upon the holder will increase or decrease theeffective depth of serrations or notches l8 and a greater or lesseramount of paste may be spread to suit conditions and the desires of theoperator.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

1. A spreader of the character described comprising a resilient striphaving a serrated edge; a U-shaped holder, formed of stifi materialrebent upon itself along a medial transverse line, for the strip; andmeans for clamping the strip between the free edges of the legs of saidholder with the serrated edge thereof projecting beyond the confinesofsaid holder.

2. A spreader of'the character described comprising a resilient striphaving a serrated edge; a U-shaped holder, formed of stiff materialrebent upon itself along a medial transverse line, for the strip; andmeans for clamping the strip between the free edges of the legs of saidholder with the serrated edge thereof projecting beyond the confines ofsaid holder, said holder having a grip formed along the bight thereof,said grip extending laterally to each side of the holder.

3. A spreader of the character described comprising a resilient striphaving a serrated edge; a U-shaped holder, formed of stiff materialrebent upon itself along a medial transverse line, for the strip; andmeans for clamping the strip between the free edges of the legs of saidholder with the serrated edge thereof projecting beyond the confines ofsaid holder, said resilient strip having a portion thereof extendingbeyond the holder along three sides thereof.

4. A spreader of the character described comprising a U-shaped holderformed of sheet metal rebent upon itself along a medial transverse line,said holder having opposed legs, and a grip at the bight thereof; astrip of resilient material, provided with serrations along onelongitudinal edge, between the free marginal edges of the legs; andmeans for clamping the strip between the legs of the holder with theserrated edge thereof projecting beyond the confines of said holder, theends of said strip being extended beyond the ends of the holder to formbuffers, said holder progressively decreasing in length as the grip isapproached from the free marginal edges of the legs.

5. A spreader of the character described comprising a U-shaped holderformed of sheet metal rebent upon itself along a medial transverse line,said holder having a grip at the bight thereof, and opposed legs, thefree marginal edges of the legs being inturned to form lips; a strip ofresilient material between the free marginal edges of the legs; andmeans for clamping the strip between the legs of the holder with thefree longitudinal edge thereof projecting beyond the confines of theholder, whereby the said lips form indentations at their point ofcontact with the resilient strip.
